The server side upgrade of MIAB from 0.52 → 0.53 went very smooth. No error messages or other problems. Actually… perfect!! Bravo!!
On the client side, for the Exchange server setup on MS Outlook, I had to use “box.domain.com” for both the server name AND the domain name in the setup fields. Outlook prompts you to enter only the “domain.com” for the domain setup field. Hope this helps somebody…
